What am I doing wrong?

I get stuck in a loop where it says “Hearthstone has been updated!” Please download the latest version. I have empy the cache on my phone, restarted it, installed the game on my SD card, tried restarting my phone. The game eventully loaded where i could choose between"I’m new" or “Sign In”. I opt for “Sign In” and the game doesn’t get past the tavern door image and i dont get to see a loading bar which says its downloading the update. I’m using a Samsung Galaxy S9 and my friend who is using a Sumsung S8 can play the game perfecvtly. What am I doing wrong?
